One of the chief of the scottish police, has recently declared that "Organised criminals have turned Scotland into a cannabis greenhouse".
According to his information, criminal organizations from the far east run a net of greenhouses in the whole country.
These grenhouses produces marijuana for the value of 1 billion euro per year. The greenhouses are manned by illegal immigrants, that work there 24 hours a day.
Many of them are farmers imported with violence from Vietnam. In the past year, more than 30.000 plants worth 40 million euro have been seized, but that's just the top of the iceberg.
The quality of the weed is extremely high, however you can't find this weed in Scotland. Almost everything is made to be exported in UK or in Europe.
